Design of a Broadband Comparator Network at $X$-Band

Design and Fabrication of Wideband Dielectric Resonator Antenna Using Low Loss Ultra‐Low Sintering Temperature Li6B4O9 Microwave Dielectric Ceramic for Wireless Communication Applications

“…[53][54][55] The bandwidth enhancement of CDRA by reducing its radius to height ratio has been demonstrated in, [56] a concept adopted from stacking of dielectric resonators to increase the bandwidth. Conversely, the CDRA with radius to height ratio >1 have also been reported for multiband operation, [55,[57][58][59] wideband, [60] diversity, [52,61,62] and reconfiguration applications. [63] Hereby, a wideband cylindrical DRA with large radius to height ratio is reported, in which the slot mode and the DRA mode at offset frequency are used to attain wide impedance bandwidth of 38.15%.…”
